Postdoctoral Research Assistant in Experimental Petrology

My research aims to define the chemical behaviour of volatiles, in particular, the halogens and sulphur, in silicate melts. In order to understand how volatiles influences the properties of a melt, the fluids they exsolve and the glasses they form, a detailed understanding of the underlying thermodynamic properties is vital. We attempt to do this by performing experiments with silicate glasses and various buffers at high temperatures and pressures.

A perfect experiment, showing a nice silicate glass, a separate,

segregated metal + metal chloride buffer, and an oxygen fugacity buffer.

I am supervised by Bernard Wood, and part of the experimental petrology group.
